Abstract
The invention discloses a multipurpose double-stage electronic scale, and the electronic scale comprises a carrier plate, a first-precision weighing module with a first supporting surface, and a second-precision weighing module with a second supporting surface and an elastic pad support part. The carrier plate is disposed on the first-precision weighing module and the second-precision weighing module in a crimping manner. The second supporting surface is lower than the first supporting surface at a free state, and the second supporting surface supports the whole electronic scale independently. When the carrier plate carries an object, the carrier object bears a force and presses the elastic pad support part, thereby driving the first supporting surface to move downwards. When the weight of the carried object exceeds a certain value, the first supporting surface moves downwards to support the whole electronic scale along with the second supporting surface. The electronic scale can serve as a body weight electronic scale and a kitchen electronic scale, and also can be effectively protected when the weight of the carrier object exceeds the maximum range of the kitchen electronic scale.
Description
Technical field
The invention belongs to electronic balance structure design field, be specifically related to a kind of multipurpose double rank electronic scale.
Background technology
Body weight electronic scale in the market, its structure mainly includes support board, display screen, regulation switch, power module and forms for supporting the LOAD CELLS of support board, its function is mainly used in human body of weighing, and be usually after carrier body weight exceedes preset value, display screen just starts to show numerical value, and this preset value is usually 5 kilograms；It addition, the maximum range of this kind of body weight electronic scale is usually 180 kilograms, scale division value is 100 grams, and error is relatively big, so this traditional body weight electronic scale is on ordinary days in addition to weighing in, substantially cannot function as its use, especially cannot be used for using as electronic scale.And existing electronic scale, its scale division value can reach 1 gram, but its range is usually no more than 50 kilograms, uses so cannot function as scale.The most also having scale division value to can reach 2 grams, range can reach the electronic scale of 150 kilograms, is to use the force cell that precision is higher and range is bigger to make, but its price is much more expensive, it is impossible to be universal.
Summary of the invention
It is an object of the invention to provide a kind of cost relatively low, both can be as wide range, body weight electronic scale that precision is low, again can be as small-range, multipurpose double rank electronic scale of electronic scale that precision is high.
The technical scheme realizing the object of the invention is: a kind of multipurpose double rank electronic scale, including support board, have the first precision of first spike and the first precision force cell weigh assembly, there is the second precision of second spike, cushion support and the second precision force cell weigh assembly；Support board crimping is arranged on the first precision force cell, and the first precision force cell crimping is arranged on first spike, and first supports the supporting surface of sole end as the first supporting surface；Support board crimping is arranged in cushion support, and the crimping of cushion support is arranged on the second precision force cell, and the second precision force cell crimping is arranged on second spike, and second supports the supporting surface of sole end as the second supporting surface；Under free state, the second supporting surface is less than the first supporting surface, and the second supporting surface individually supports whole electronic scale；During support board carrying object, under support board stress, compression elasticity advance expenditure part and then drive the first supporting surface move down；After carrier heavily exceedes to a certain degree, the first supporting surface is displaced downwardly to jointly support whole electronic scale with the second supporting surface.
In such scheme, cushion support includes screw thread spring, the upper advance expenditure part being arranged on screw thread spring top and is arranged on the underlay support of screw thread spring bottom end；Upper advance expenditure part is fixedly installed on support board diapire, and the crimping of underlay support is arranged on the second precision force cell.

(embodiment 10)
The present embodiment is substantially the same manner as Example 1, difference is: as shown in Figure 32 to Figure 34, and each second precision assembly 3 of weighing includes second spike 31, cushion support the 4, second precision force cell 32, insulation shell 33, the placing chamber 34 being arranged in insulation shell, covers placing chamber bottom end opening and have the elastomeric cap 35 of center trepanning 351；Second spike 31 in the present embodiment includes the pillar 36 being arranged in the trepanning of elastomeric cap center and rotates the support wheel 362 being arranged on pillar 36, and the second precision force cell 32 crimping is arranged on the top of pillar.
Cushion support includes pressing plate 47, support rod 48, torsion spring 49 and block piece 100, and block piece 100 is fixedly installed on support board diapire；The top of support rod rotates and is arranged on support board diapire, and the bottom of support rod rotates and is arranged on pressing plate 47；Pressing plate 47 crimps and is fixedly installed on the roof of insulation shell.One end of torsion spring is connected on support board diapire, and other end hook joint is in support rod；Support rod is obliquely installed relative to support board, and when support board does not carries object, support rod, under the elastic force effect of torsion spring, is crimped on block piece 100, and when carrying object on support board, the support rod in accompanying drawing 33 is rotated in the clockwise direction, so that support board moves down.
In the present embodiment, the root edge supporting wheel 362 crimps on the ground, and this support takes turns 362 root edge place horizontal planes as the second supporting surface 30.In the present embodiment, the existence supporting wheel 362 is the deformation in order to coordinate support rod 48 so that whole weighing process is in stable poised state.
Under free state, the second supporting surface 30 is less than the first supporting surface 20, and the second supporting surface individually supports whole electronic scale；During support board carrying object, compression elasticity advance expenditure part under support board stress, cushion support oneself height diminishes, so that support board and the first supporting surface move down；By selecting suitable torsion spring, when can make carrier body weight less than preset value, when e.g., less than 20 kilograms, second supporting surface 30 is consistently lower than the first supporting surface 20, and the second supporting surface individually supports whole electronic scale, and now the first precision assembly of weighing is unsettled, do not play weighing effect, the present embodiment is now that the second precision assembly of weighing acts the effect of weighing, and minimum precision, up to 1 gram, can be used as electronic scale；
After carrier heavily exceedes to a certain degree, after such as more than 20 kilograms, first supporting surface is displaced downwardly to jointly support whole electronic scale with the second supporting surface, now the first precision weighs assembly and the second precision is weighed the equal stress of assembly, all act the effect of weighing, by the calculating of intelligent control circuit, the weight of now carrier can be demonstrated on a display screen, now minimum precision is 100 grams, so the present embodiment is also used as body weight electronic scale and uses.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change that these connotations belonging to the present invention are extended out or variation still fall within protection scope of the present invention.
